I have 2 chargers, the stock one that came with my P2 V3.0 and an after market one that could charge 3 batteries at once.   Is it safe (and not harmful) to the new Phantom 3 battery to use these chargers with the new batteries?

Well... sorta, you could.  The P2 charger will just take a lot longer.  The aftermarket is a risk.

The "Official"  position:
- DJI takes no responsibility if the battery is charged using a non-DJI charger.
- Use only the official DJI Phantom 3 Advanced charger
- The Phantom 3 Advanced comes with a 57-watt charging unit and the Phantom 3 Professional comes with a 100-watt charger, the latter of which allows for shorter charging times.

No you can't.  
Ignore the previous answer.
The voltages are completely different.
11.1V for the P2 vs 15.2V for the P3.

That's not true ... The real battery charger is inside the battery and "battery charger" is a simple power supply. If P2 (3s lipo) batt charger has enough output voltage and power to supply more than 15V (4s lipo) then it can work fine.

"If P2 (3s lipo) batt charger has enough output voltage and power to supply more than 15V (4s lipo) then it can work fine."
So what is the output voltage on your P2 charger?
Mine says 12.6V.

Both of mine are 12.6v  as well.   Will they even slow charge?

No .. you can't use them.
Despite what some may have told you, you need to use a Phantom 3 charger to charge a Phantom 3 battery.

Did anyone try? If so, what happened?

the p3 battery has different connectors than the p2.  Photographic evidence is listed here:

Just for info, all depends how internally the battery manage charging. A 4s battery is rated at 3.7V * 4 = 14.8 nominal but eaxh cell is full charge at 4.2V so at the terminals you get about ~17V. To charge all the 4 cells you need minimum 17.8V). ~1V of margin is needed to let protection diodes (-0.6V) working. But if the battery internally is balancing cells charging each one separately, it just need 4.2V. I don't know how DJI battery is working under the hood.

If you have stock DJI chargers for P2 and P3, the charging cable connectors to the battery are different sizes and you can't connect the P2V+ charger to a P3 battery.  Similarly, you can't physically connect a P3 charger to a P2V+ battery.  I've tried with the AC chargers unplugged from the wall just to make sure I never accidentally did it.  It can't happen due to the different size connectors used on the chargers and the batteries.

So what would happen if you rigged  a phantom 2 battery onto a p3

This isn't right.  I remember this was discussed in a thread a couple years ago.  The P2 series cells are 3.7v each nominal charge.  But the P3 series cells are 3.8v each nominal charge.  That's because the technology improved.  I am stating this from recalling what was in the thread two years ago, don't crucify me if I'm mistaken  :-D  

Edit:  It's still listed that way on the DJI specs pages

If you want to speed up your Phantom 3 intelligent flight pack charging, do what I and others have done.

Buy a second OEM DJI 56w or 100w charger. Do the right thing, use the proper equipment for the job at hand.

Having two 100w chargers has been a blessing, for my four Phantom 3 Pro', intelligent flight packs.

i bought a 100W dji official charger of ebay with a 4 battery docking unit for a good price
i now have 10 batteries
so i use the 100w on one docking station for 4 x batteries and the stock 56w on another docking station for 4x batteries

That sounds like you have all your charging needs well under good control.
Yes, having the second charger is very helpful. Particularly good for charging a flight pack and RC at once.
I need to get three more flight packs for a total of 7, which is how many the Plasticase Nanuk 945 holds.
